114 MHz LVDS clock source with MEMS reliability
The DSC1103CI5-114.0000 is a standard XO (Standard) oscillator from Microchip's DSC1103 series, delivering a fixed 114 MHz output in LVDS format. The MEMS resonator base gives it better shock and vibration tolerance than a quartz crystal — useful if this board goes into a panel that gets shipped or a machine that shakes. Supply voltage spans 2.25V to 3.63V, so it runs off a common 2.5V or 3.3V rail without an extra regulator. The Standby (Power Down) function on pin 1 drops current to 95 µA max when the clock is not needed — handy for power-cycled or battery-backed systems.
Industrial temp grade and ±10 ppm stability
Frequency stability is ±10 ppm across that range — tight enough for a 100BASE-TX Ethernet reference or a mid-speed SERDES lane clock. Maximum supply current is 32 mA while active; the LVDS output pair drives a 100-ohm differential termination directly, so no external bias resistors are needed on the receiver side.
Active production — no end-of-life pressure
Microchip lists the DSC1103CI5-114.0000 as Active. It is suitable for both new designs and ongoing production — no need to stockpile or qualify a replacement. The 6-SMD No Lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard MEMS oscillator footprint shared across the DSC1103 family. The pad layout is the same as many quartz XO packages in this size — a board designed for a 3.2x2.5 mm XO will take this part with no layout change.
